Extracting JH files will fail if the JH branch contains /
This is discovered at !99479 (comment 1217927237) and the failing job was https://gitlab.com/gitlab-org/gitlab/-/jobs/3509627927
mv: cannot stat 'gitlab-vs/upgrade-sprockets-jh-*/jh': No such file or directory
I am not sure, but /
might be part of the filename, and we clearly need to handle this carefully when using shell script.
